I am about to do a 6 inch lift and relace my stock tires with 35 inch Mickey Thompson ATZ's. Will I be disappointed in the change in performance? Will a hypertech reprogram help?

You will probably be disappointed in the performance and it will be harder on drive train parts.

 

Hypertech - NO

 

Gears and Blackbear tune - Yes

 

 

Welcome to the site by the way and where are the pics?

The truck will definately feel more sluggish, but a programmer should help some. You could always regear.

Another vote for regearing. Go with 4.10s AND a reprogram. :thumbs:

3.73's will be ok for now, but it will be the equivalent of swapping them out for economy car gears. 4.10 would fair better, but I would go 4.56 which would return your final ratio to stock. Not really needed right away though as most people never re-gear.

I am currently running 3.73's with 35's with the 5.3 and its not bad at all. She still moves fine. Having said that, I am still re-gearing to help relieve the stress on the driveline. I am going with a 4.56 if I decided to stick with the 35'5 or 4.88 if I go with a 37. A tune will also help.

If you have 32 or 33 do u need to re-gear. I have 5.3L with 3.73. My tire size is going to be 275 or 285/ 55/20 KMC XD Rockstars or Monsters

you will be dissapointed. and with the 4spd trans DONT waste your money on 4.10s... get 4.56 or 4.88

 

i had the 5.3L, 4spd, 4.10s and 35s and the truck was gutless. Sure... it still moved "ok".. but it was a slug. No passing power, couldnt accelerate on the highway, and it would fall flat on its face trying to accelerate with an EMPTY single axle 10' trailer attached to it.

 

i went with 4.88s and finally had a truck again.

 

worried about gas mileage?? i got BETTER highway gas mileage with my 4.88s and 35s than i did with my 4.10s and 35s .... and yes my truck was a highway driven DD.

 

take it from someone who has been there / done that, plan from the start to regear... and dont waste your money on 4.10s!! there's no speculation or 2nd hand info in this post fwiw.

SOB! this is an oooold thread

eric... i cant say whether you can or cant install the gears because im not sure what the extent of you mechanical ability really is. generally, gears are the type of thing that "if you have to ask, you cant install them". gear installs require a few specialized tools, a lot of patience, and experience! if you dont know someone who has done a gear install to watch over your shoulder, dont even bother...

 

find a good local shop, talk to them... they'll tell you what brand they recommend and have good results with.

 

both 4.56s and 4.88s will work. i highly recommend 4.88s and have heard many people say they wish they went with 4.88s instead of 4.56s.

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
